2 Claims.

This invention relates to an improvement in ski equipment and in particular to an attachment by which a non-slipping grip may be obtained in climbing and to prevent side-slipping on icy surfaces.

An important object of this invention is to have an easily adjustable and removable ski device which may be removed or put on with a minimum of effort. This gives a skier an added advantage in racing or in forward movement of any find.

Another object is to have the blades swing on an axis so that they will not impede the forward movement of the skis if the apparatus is not removed.

A still further object is to perfect a clamping mechanism that is adjustable, resulting in a device capable of fitting any size ski.

Another important object and improvement is to perfect a device in such a way that it will not tip the ski if a hard surface such as ice or wood is stepped on. With my invention the ski would slide forward slightly and rest in its natural or fiat position.

With these and other objects in view that may appear while the description proceeds the invention consists of the construction and arrangement of parts more specifically set forth, claimed and shown in the accompanying drawings forming part of the application and in which:

Fig. 1 is a plan view of the invention attached to a fragmentary view of the ski;

Fig. 2 is a rear elevation view of the invention clamped to the ski;

Fig. 3 is an elevation view of the device unattached and with the clamping mechanism open;

Fig. 4 is an end elevation view showing the movable dog in position to grip the skiing surface.

Fig. 5 is an elevation view of the invention with the clamping mechanism slightly changed in shape to permit clamping on a ski with a curved upper surface.

Referring more in detail to the drawings, it will be seen the invention consists of a brake mechanism which is a dog I, attached to a pin 2, so that it may swing on this axis at will. The dog has a slightly curved and sharpened edge 3, to facilitate its grip on the skiing surface. The aforementioned pin is housed in the plate l2, which supports the dog and pin and is attached to the clamp plate 4.

The said clamp plate has an edge 6, to grip the ski on one side and work in conjunction with the adjustable clamp 1, on the opposite side of the ski to afford a firm grip on any size ski. This clamp l, is provided with a screwthread which is moved in the housing 8, until any desired distance is reached from the clamp edge 6, to the opposite clamp edge I.

The whole is operated by the lever 9, which throws the clamping lock into a locked or open lized for gripping the skiing position as desired. This is accomplished by the pin l0, serving as a fulcrum around which the lever 9, pivots and so pulls the housing 8, into a forward position thus forcing the clamp I, and clamp 6, together and into the ski sides.

The position of the device is shown in its relative position to the ski II. It rests on the upper surface of the ski immediately in front of the boot clip where a maximum offorce can be utisurface. The blade swings in position on the outside of the ski resting in a horizontal position on the surface of the snow when the ski is in forward movement and dropping into a vertical position locked against the housing l2, by cutting into the skiing surface when the movement is in a backward direction.

While the specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.

I claim:

1. A ski hill climbing device comprising a clamp plate adapted to extend transversely of the ski and having a hook at one end to engage the side of the ski, a bracket plate attached to said clamp plate having one end extending beyond the side of the ski and bent to provide a U-shaped bracket having its open end pointed towards the rear of the ski, a pivot pin mounted in said bracket, a brake arm mounted on said pin adapted to swing in a vertical plane parallel to the side of the ski, said brake arm being limited in its forward movement by engagement with the back of said bracket, a clamping member for engaging the opposite side of the ski, and a throw lever pivotally connected to said bracket plate and said clamping member for moving said clamping member and said clamp plate into clamping engagement with the ski.

. 2. A ski hill climbing device comprising a clamp plate adapted to extend transversely of the ski and having a hook at one end to engage the side of the ski, a U-shaped bracket extending beyond the hooked end of said clamp plate having its open end pointed towards the rear of the ski, a brake arm pivotally mounted in said bracket to swing in a vertical plane parallel to the side of the ski, said arm being limited in its forward movement by the back of said bracket, a clamping member for engaging the opposite side of the ski, and a throw lever pivotally connected to said clamp plate and said clamping member for drawing said clamping member and said clamp plate into clamping engagement with the ski, said lever having its end extending over said bracket when in clamping position to limit the upward movement of said brake arm.
